Abstract
Feature selection and fusion is of crucial importance in multi‐feature visual tracking. This study proposes a multi‐task kernel‐based sparse learning method for multi‐feature visual tracking. The proposed sparse learning method can discriminate the reliable and unreliable features for optimal multi‐feature fusion through using a Fisher discrimination criterion‐based multi‐objective model to adaptively train the kernel weights of different features such as pixel intensity, edge and texture. To guarantee a robustness of the sparse representation method, a mixed norm is employed in the sparse leaning method to adaptively select correlated particle observations for multi‐task sparse reconstruction. Experimental results show that the proposed sparse learning method can achieve a better tracking performance than state‐of‐the‐art tracking methods do.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
